Hi thanks a lot for your help. But how do u get 21u? Then how u derive 4u is $216? Sorry

3/4 of D was given to E. Which means 9u+180 was given to E. E originally had 12u. So now will have 12u + 9u + 180 = 21u +180

Then E gave 1/3 to D. 1/3 of E is 7u+60. So, D will now have 3u+60+7u+60 = 10u + 120. And E will be left with 14u+120. The difference between D and E is 216

Wa!!! You guys are so good!! Thank you for all your help. Can explain to my gal. Thank you all

Appreciate a lot! Thank you

Hi thank you for your help

not sure if i'm right cos i din use all the info given.. anyone got a different answer?

Hi Vera how did u get the first ratio of 3:5?

"total area of G n H is 60% of F"... G + H : F -> 6:10 ie. 3:5

Oh now I get it!!

Thank you so much. Now I start to see the picture. Sorry I am very dumb

u r most wlcm. i respect ur effort. i dun think u r dumb at all. :)

Thank you for your encouragement. I need to put in more effort

Trying to use all info but not as direct as Vera Koh's method.

Thanks a lot

Need help please

If you take a look at Micheal Lim's qn posted earlier 'Polly had 360 more dolls than Ariel at first...', you'll find that it is similar to yours. The only difference is the info given at the end. In that question, the total at the end is given. In yours, the difference is given. The model for the problems can drawn in the same way.

Thank you very much

Let me know if u need further help. Or you can post your model here and I can help you along.

Benjamin your steps are correct. There is a change of 3 units from 3:7 to 6:10... The age difference remain the same i.e. 12 yrs .. Therefore 3units=12... 1 unit=4 Arabelle is 3units=12 years old. A

Thank you all for helping.

Yuen Mei, may I know where does the 6 units came from? Thanks.

6 units is for 12 years later... The QN is asking what age is Arabella now.. So I think the answer is 12yrs old---

Hi .. Sorry I did not understand the method. Pls help in a simpler way.

Yes. .... age now is 12 years old. 3 units not 6 units.

Thank u so much Mayuree Thongpan. Now it's so clear.
